All of the numbers in the shaded part of the line have two characteristics:
==> X >= 0
==> X <= 20
This can be written as a single inequality with x in the middle, but when I type it, Brainly won't accept the characters, and says there's an error.
Here it is in words:
0 (less than or equal to) x (less than or equal to) 20 .
7 weeks. Total cost is 239 minus 127 she has saved leaves 112 more she needs to save. 112 divided by 16 a week is 7 weeks until she has enough money.
Step-by-step explanation:
TRIANGLE 1
c = 2√5
= 2 × √5
= √4 × √5
= √20
a = 2
b = ?
b² = c² - a²
= √20² - 2²
= 20² - 4
= 400 - 4
= 396
b = √396
= √36 × √11
= 6 × √11
= 6 √11
TRIAGLE 2
a = 12
b = 6√11
= √396
c = ?
c² = a² + b²
= 12² + √396
= 144 + √396²
= 144 + 396
c = √540
= √36 × √15
= 6 × √15
= 6 √15
Sorry if i wrong. Im beginner in USA server
11 and 2/11 because 46 divided by 11 is 44 plus 2 is 46
